Repairing an Ejector Plate for a Die Casting Machine

Columbia Machine Works repaired this ejector plate for a die casting machine. The first step was to grind the cracks out of the plate and weld them up. We then machined the closing cylinder mounting surfaces, ensuring that any welding on the cracked cylinder mounting holes were machined out. Pictured here, the next step was line boring the guide rod …

Fabricating and Machining Two Large Rings

Columbia Machine Works was contracted to fabricate two 11′ diameter rings. These rings were burned out on our CNC plasma table out of two pieces of 2″ A36 plate, then welded at the seams with 100% joint penetration. They were then put on the boring mill to receive 40 equally-spaced, drilled and counterbored holes around the full diameter. Then we …
